i want to create a project manager for my ai agency, using mastra.ai and mongodb for observeable memory and vector store as well. the agent needs to have acees to the web with exa.ai web search. it needs to keep linear and github in sync, as well as monday.com. it is to delagate work, not complete work,  after it breaks down the task into pieces , it then passes the work outto its teammates.  from then it monitors the  the progress of the other agents. if they get stuck he is  too assist and

    // The subarray that maximizes (max - min) is always the ENTIRE array,

# Role and Objective
Craft a vivid, compositionally coherent illustration prompt in a fineline black-and-grey Chicano tattoo style rendered as though drawn on vintage parchment.
# Instructions
- Produce a detailed scene description that includes every required subject, object, and stylistic cue.
- Preserve the intended Chicano tattoo-art sensibility: stylized, dramatic, expressive linework, monochrome palette, heavy stippling, and high-contrast shading.
- Ensure the composition feels balanc

# 本番DB変更手順メモ

## 前提

- Webアプリケーション開発における本番DB変更を対象とする。
- 作業は一人で実施する。担当者決定、承認者決定、監視担当者決定、会議体調整は扱わない。
- 対象はスキーマ変更、データ変更、スキーマ変更とアプリケーション変更が同時に必要な作業。
- SQL、マイグレーション、確認クエリ、ロールバッククエリ、実行ログを作業単位で保存する。
- DBMS固有のコマンド名はこのメモでは固定しない。採用DBの公式マニュアルで該当構文、ロック、トランザクション、バックアップ、リストアを確認する。
- 本番DBで最初に実行する作業を作らない。ステージング、複製環境、ローカル再現環境、本番トランザクション内検証の順で実行前確認を増やす。

A complex, vintage Chicano tattoo-style graphic composition featuring a classic 90s luxury lowrider sedan cruising low through a Phoenix barrio summer night, wire spoke wheels shining, whitewall tires, chrome bumpers, and desert dust trailing behind it. Above the car looms a large menacing skull wearing aviator sunglasses and a snapback cap reading “PHX WESTSIDE,” surrounded by palm trees, saguaros, power lines, dice, roses, and heat-wave ribbons. Elaborate gothic typography reads “SUMMERTIME CR
